Its incredibly frustrating when the scale doesn't budge when you KNOW it should. So much of what is measured on the scale is not actual fat loss. Our body weight changed drastically because of water retention, etc. If you are not already doing it, try using a tape measure around various areas of your body.

What I've also done is buy clothes one size too small to wear comfortably and then I try that on every couple of weeks until it fits perfectly. That is a more objective measure of actually body composition changes than a number on a scale.

Good luck to you
